What is the difference between heated and cold rollers and what does the term ‘silvering’ mean?
Some Pressure Sensitive Films if applied cold can leave a slight “silvering” effect on the print. If approx 40c heat is applied on the rollers when this film is applied the silvering disappears.
This is due to the fact the glue on the film is softened and warmed when applied and speeds up the polymerisation process. Over time the silvering when applied cold does slightly reduce but does not totally disappear.
Not all films need heat and vinyls and vehicle wrap film work better when laminated cold. Most sign makers therefore feel that a cold machine will be fine because the silvering effect is minimal. Photographers and Exhibition graphic suppliers are more critical and therefore require a heated top roller for a perfect finish.
Our Easymount range of cold systems have rubber rollers and the heated roller machines have a silicon rubber roller.
